Application led September 14, 1887. Serial No. 249,711.

To all whom it 71mg concern.'

Be it known that I, JULIUs SCHEMMEL, a citizen of the United States, residing at Chippewa Falls, in the county of Chippewa and State of Wisconsin, have invented a new and useful Improvement in Velocipedes, whereby they may be adapted to run on ice or snow, of which the following is aspecitication.

My invention relates to a class of velocipedes having three runners and a spur-wheel. I attain the objects of my invention by the mechanism illustrated in lthe accompanying drawing, in which a perspective view is shown.

' A saddle, A, resting 0n al spring, B, is mounted on a frame in which revolves awheel propelled by treadles E E. The-frame is supported behind by two runners, F F, and yin front rests upon a collar, G,on an upright shaft, H. The upright shaft H has at its lower end va runner, I, and at its upper end handles K, by which the shaft and runnermay be turned to steer the machine. At the rear end of the frame,atL,is hinged alever extending forward and terminating in a handle,N, infront of the seat and having two arms extending backward to support a spur-wheel, M,having teeth t0 engage the ice or snow. This wheel is raised or depressed by means of the handle N. On the handle N is a spring, O, which, by being adjusted by a hand-wheel and screw to press on the frame, holds the handle up and. adjusts (No model.)

the traction of the wheel M. On the side of the wheel Mis a flange having teeth or sprockets to engage the links of a drivechain, Q, which derives its motion from drive-wheel D. It is operated by a person sitting on the seat and turning the treadles with his feet, as in a bicycle. The motion of the drive-wheel is conveyed to the spur-wheel by the chain. The teeth of the spur-wheel catch in the ice as it revolves andv propel the velocipede on its runners. When it is desired to slide without propulsion, the spur-wheel is raised off the ice by its lever. When it is desired to stop suddenly, the spur-wheel is held vfirmly on the ice and the .treadles held or reversed with the
